Just trying to understand - why are you saying this is a pmix problem? Obviously, something to do with mpirun is failing, but I don't see any indication here that it has to do with pmix.
Can you add --enable-debug to your configure line and inspect the core file from the dump? > On Jan 31, 2021, at 8:18 PM, Andrej Prsa via devel <devel@lists.open-mpi.org> > wrote: > > Hello list, > > I just upgraded openmpi from 4.0.3 to 4.1.0 to see if it would solve a weird > openpmix problem we've been having; I configured it using: > > ./configure --prefix=/usr/local --with-pmix=internal --with-slurm > --without-tm --without-moab --without-singularity --without-fca > --without-hcoll --without-ime --without-lustre --without-psm --without-psm2 > --without-mxm --with-gnu-ld > > (I also have an external pmix version installed and tried using that instead > of internal, but it doesn't change anything).
